Resumen:
Electron emission due to grazing scattering of fast protons from LiF and KCl surfaces is studied under axialchanneling conditions. The differential electron emission probability is calculated within a distorted-waveformalism, taking into account realistic channeled trajectories. For electronic spectra along low-index crystallographicdirections, we find that channeling effects on the electron emission yield depend strongly on thepenetration rate of projectiles into the solid.
